In this embodiment, one side of the side plate is provided with a connecting lug 6, and the other side is reserved with a connecting area 7 connected with the connecting lug 6, so that the connecting lug 6 is connected with the connecting area 7, the side plate is enclosed into a semi-closed box body with openings at the upper end and the lower end, and the cover plates at the upper end and the lower end of the side plate are folded inwards along the folding parts of the cover plates and the side plate to form the honeycomb carton. The honeycomb carton adopts the nail case mode, and engaging lug and joining region utilize the nail to link together.

In this embodiment, the honeycomb paperboard 10 includes a first face paper 1001, a second face paper 1002 and a honeycomb core 1003, wherein the first face paper 1001 and the second face paper 1002 are made of kraft paper, and the kraft paper has a tough texture, high burst strength, high ring crush strength and high tear strength, and also has high water resistance; the honeycomb core is preferably bonded by a plurality of hollow regular hexagonal prisms, the regular hexagon has a compact structure, each side is equally stressed, the stress is easily dispersed, and the borne impact is larger than that of other structures. The first face paper and the second face paper are covered on two sides of the honeycomb core through glue to form the honeycomb paperboard.

In this embodiment, the thickness of the honeycomb paper board 10 is 6mm, the thickness of the honeycomb core 1003 is 5mm, and the thickness of the corresponding first and

second face papers

1001 and 1002 is 0.5 mm. The reduction in thickness of the honeycomb paperboard 10 means a reduction in consumption of raw materials for making the honeycomb paperboard, so that production costs can be saved. But under the prerequisite that reduces honeycomb cardboard thickness, the compressive strength who prevents the honeycomb carton descends by a wide margin to prevent the condition that the carton can not be used from appearing. Under the premise, the inventor improves the bending part for connecting the adjacent side plates of the honeycomb carton.

In this embodiment, the outer impressions on the outer side of the carton comprise a first outer impression 4 and a second outer impression 5; the first external impression 4 and the second external impression 5 are respectively positioned at two sides of the internal impression 8 of the side wall of the carton, and the depth of the first external impression is greater than that of the second external impression. The first outer indentation 4 and the inner indentation 8 realize that the side plate is continuously bent to a double-folded state along the bending direction in the use state in the recovery and flattening process, and the second outer indentation and the inner indentation realize that the side plate is bent to form a bent part when being recycled again or continuously bent to the opposite direction of the bending direction in the use state to the flat and straight state of the paperboard.

The depth of the inner impressions 8, between the first outer impressions 4 and the second outer impressions 5, may be 2.5 mm. Both the inner 8 and outer impressions are parallel to the edge of the lateral plate 2.

Because the side plates are bent in the opposite direction to the bending direction in the use state or in the bending direction in the use state in the recycling and flattening process, even if the side plates of the side walls are bent in a flat, straight or folded manner, the deformation of the side plates after bending to the flat and straight is relatively small, and the deformation of the side plates after bending to the folded manner is relatively large, the depth of a first outer indentation on the side plate on one side in the folding direction is relatively large, the damage of the honeycomb carton during storage of the flattened honeycomb side plates can be effectively reduced, the depth of a second outer indentation on the side plate on the flat and straight side is relatively small, the structural damage degree of the honeycomb paperboard is reduced, and the compression strength of a bending part of the box body formed by bending the honeycomb side plates during reuse is further ensured; the inventor adjusts the structure of the inner press mark and the depth of the two outer press marks, so that the honeycomb carton can be recycled, the service life of the honeycomb carton can be prolonged, and the use cost of the carton can be reduced.

The quality of the indentation bending quality is greatly related to the indentation depth, namely the indentation angle, the indentation is too shallow, namely the depth is smaller, the section is cracked due to overlarge strain of the indentation part on the surface paper of the honeycomb paperboard 10 in the bending process, and the indentation is too deep, namely the depth is larger, the paperboard is cracked in the bending operation or the local strength along the indentation line is excessively reduced, so that the bending cannot be performed; therefore, the depth of the outer indentation is 1/3-1/2 of the thickness of the paper board of the honeycomb carton, so that the situation that the facial tissue is cracked due to excessive strain can be avoided, and the strength required by bending and the whole carton compressive strength required by the carton in the using process can be ensured.

In this embodiment, the inner indentations, the first outer indentations and the second outer indentations are designed to meet the requirement that the honeycomb paper board is reduced in thickness, and the honeycomb paper board is recycled by adjusting the structures of the inner indentations and the depths of the two outer indentations.

In this embodiment, the cross-sections of the inner and outer indentations have a U-shaped configuration. The middle part of the indentation of the structure is of a circular arc structure, so that the honeycomb paperboard can be compressed or expanded to a larger extent in the folding process of the indentation.

The two sides of the inner indentation 8 are provided with pre-pressing lines 9, and the depth of the pre-pressing lines 9 is less than or equal to 1 mm. The pre-pressing line 9 is arranged to perform shallow indentation on the honeycomb paperboard 10 in a first step, so that the honeycomb paperboard 10 is softened in the area of the pre-pressing line 9, and then external indentation with a deeper depth can be performed in the area, thereby avoiding line explosion. Based on the above principle, the pre-pressing line 9 can be arranged on one side of the outer indentation.
